About Sight glass
Sight glass is used for looking inside a process vessel or pipeline. For many years the Chemical Processing and related industries had only one choice in selecting a sight glass; a single thickness or glass bolted between two flanges in either the form of a round flat piece of glass or tubular cylinder. Many of these types of sight glasses are still in use today.
Today's modern sight glass is much more sophisticated to provide maximum safety under high pressure and temperature operations and a wide thermal shock range. We insist that it must also be capable of resisting any blow outs or ruptures.
For Over 60 Years...
Cyclops Industries Inc. of South Charleston, West Virginia has been designing and engineering sight glass, sight flow indicators, spray rings and sight lights, that provide maximum safety in high temperatures, high pressure, corrosive and volatile processing operations. We can also provide a Safety sight glass to replace your existing single lens sight glass.
